[PATCH] USB Storage: endpoint toggles and reset delays

This patch does two things to help reset recovery.  It started life as
as496 and was rediffed by me.

First, the patch checks the result of a CLEAR_HALT request and doesn't reset the
endpoint's data toggle unless the request succeeded.

Second, it reduces the timeout for a device reset from 20 seconds to 5
seconds.

If all goes well, then I've finally figured quilt out and this patch should
apply cleanly.
